Oh absolutely. It needs to be well done, which means you do that at a moment for maximum surprise effect, and then don't use it again, at least for some time. You could use other uncontrolled psychic stuff as well of course, like reading a guys' mind when you don't want to, that kind of things. The most important would be to keep it optimal, to still leave some margin to the player to choose his own actions, get the spotlight from time to time using his choices in the first place, but not let it go to the other extreme where the other players would just become spectators or secondary roles. That would suck.And with that kind of backstory, or something as neat, destitution can be well done and fun. But it does need to be well done to be fun.
